more doubles in addition to attaining 50 home runs. Prince Fielder, at 23 years and 139 days, was the youngest player to reach the milestone while Bonds, at age 37, was the oldest. Pete Alonso and Aaron Judge are the only players to hit 50 home runs in their rookie seasons. Due to the infrequent addition of members into the 50 home run club, Baseball Digest called it "a restrictive fraternity comprising slugging elite" in 1954, when there were only six members. Of the seventeen members eligible for the Baseball Hall of Fame, eight have been elected and three were elected on the first ballot. Eligibility requires that a player has "been retired five seasons" or deceased for at least six months, disqualifying four active players and five players who have been retired for less than five seasons. Some believe the milestone has become less important with the large number of new members; fifteen players joined the club on a total of 24 occasions from 1995 to 2010. Additionally, several of these recent members have had ties to performance-enhancing drugs.
